1592, 1608 or 1995 for my 124 Special T - my 1st post
Posted: January 14th, 2015, 6:58 pm
Hi all,
This is my 1st post since joining and I'm in need of some guidance in putting together an engine for my 124 Special T saloon.
I've recently bought the car, it's taxed, MOT'd and very solid with the exception of the paint and has done just over 33,000 miles from new!!!
So currently it has a good low mileage 1592 twin cam in it, all standard. With the car but not fitted came a waffle manifold and a correct pair of 40IDF Webers and I also have the required cam driven distributor and exhaust cam/cam box to suit.
Also I have amassed a collection of engines and parts roughly as follows:
2 x good 1995cc blocks/cranks/rods/pistons (standard flat top pistons)
1 x good complete 1608cc engine, I have stripped this and all bores are good, crank is good, cams are good etc. It's fitted with the 4.5mm domed pistons.
1 x complete 1438 engine, unknown condition
1 x Strada 105TC cylinder head with the 43.5mm inlet valves (this has been mildly ported/polished in keeping with GC's recommendations within the tuning manual)
Various cams, all standard Fiat and used but good, narrow lobe 1608 (inlet/exhaust), narrow lobe 1438 (inlet/exhaust), 1608 exhaust cams with distributor drive and 1995 wide lobe (inlet/exhaust).
So, what's the best combination for the best power/torque? I realise that none of the above is going to give me earth shattering performance but what I'm trying to achieve is the best results from what parts I have.
As I see it I have 3 options:
Keep the 1592, add Webers, 105TC head and 1608 exhaust cam/distributor etc.
Assemble the 1608 and add the above parts
Assemble one of the 1995's and add the above parts.
Initially I was keen to keep the original low mileage 1592 "as is" and build one of my spare engines, therefore still having the untouched original engine to go back in the car at a later date to conserve originality but if it's the best unit to use then so be it!
I have heard that the 1995 is not necessarily the best option due to the taller block and increased weight?. What are the advantages/disadvantages to the 1608 over the 1592? Can the 1608 80mm domed pistons be fitted to the 1592 block to increase compression ratio?
Your thoughts please...
I look forward to any advice received from you guys.
Thanks
Lee
